Abstract
Methods for embedding photocatalytic titanium dioxide in concrete surfaces to reduce pollutants via photocatalytic reactions are provided herein. One method includes applying an amount of concrete treatment compound to an upper surface of the concrete, the concrete treatment compound comprising a mixture of a liquid carrier compound with a titanium dioxide (TiO2) photocatalyst.
